Why Do We Need to Learn Reactive Programming?

Nowadays, most software deals with data that’s only available over time. Websites load remote resources and respond to complex user interactions, servers are distributed across multiple physical locations, and people have mobile devices that they expect to work at all times, whether on high-speed Wi-Fi or spotty cellular networks. Any serious application involves several moving and asynchronous parts that need to be efficiently coordinated, and that level of coordination is difficult to achieve with the programming techniques that we currently have. On top of that, we have to deal with issues that have always been there, for example, servers crashing, slow networks, and software bugs.

We can’t afford to keep programming applications in the traditional way that we always have. That traditional way worked for a while, but now it’s time for us to use a new approach, that is, RxJS.
